| Abstract: | The fracture behaviors of DO3-ordered Fe-28Al alloys with or without V addition were studied. The results show that addition of element V into Fe-Al alloy can improve the mechanical properties of the alloy. Contrasted with transgranular fracture of Fe3Al alloy at room temperature, the Fe3Al containing V has intergranular and transgranular cleavage mixed fracture mode. The theoretical calculation conforms that V addition could increase cleavage strength of Fe3Al alloy from 98.405 7 kJ/mol to 173.144 5 kJ/mol in 〈111〉 direction and from 29.660 4 kJ/mol to 47.673 0 kJ/mol in 〈100〉 direction. |
